A m.%jcr goeL of the N!C is to try to satis 'r 
. 4.0 those information 
needs upon ?nich the success of the "network o.xi';orir. ent" will be most 
dependent, The UIC, then, is concerned with supplying information and 
documentation services -- as contrasted to other possible sc,:.'vices such 
as project managemc.nt, ccmpi!ing, etCo 
User needs of concern to the ,"IiC are as fo!1o'.,,s: 
(1) Creation of Dce.w,ents 
Users will need to create docu:ents for use by other network users 
8red for their own use. After a docLmont hss been created the user 
wish to inspect a2zd/or .:odi.y it. 
(2) Inspection of I)oc ..... .:, 
Users will need to exa.r,ine (i.eo read) ........ 
o. ocu.,C:p.u, tO vs.riotls 
Such an examination may be a relude to subsequent modification 
or other retrieval actions. 
(3) Modification of Documents 
Usera will need to modi:'y doe.'tent, of their own cremation, whether 
to co'-'rect errors, add, delete, change, or merge. ?ioy ',,'ill also desire 
to modi ' doeu-','ents created by others. 
Searching for Douuments 
The user w3._, need to be able to scan collections of doc%ments to 
search-for items relevant to his work at a given moment. If a search is 
successfrei the user will desire to insneet and/or ".' ' .... , 
that he  
SO!eCS.

various for;ns -- e.g. h.2'dcopy (paper, :ai. crofj.!:a) or softc:ol'.y (corputa 
files). 
III SERVICES 
To satisfy these needs the [iC is e;:pected %o provid th oowin 
services: 
(!) Access to NiC Servicers 
This will be initially provided via the network md via "dialup" 
Dataphone lines for ty?ewriters and low-speed CR? termi:a.ls. Later 
access.will be provided via the network for hi6;h-performance CRT 
terminals. 
(2) A Repository for a Collection of Domments 
This collection will consist of documents contributed by network 
users or collected by the staff of the NIC. Elements of the collection 
will include research reports, user's uids, system aud progrs 
descriptions, actual code, and papers of general user interest. The 
collection will be kept in various versions: 
In hardcopy, as microfilm 'and paper nzsters held at the NIC. 
Replicas would be routinely distributed to each network site 
and other selected organizations for the users. 
Special microfilm replicas of selected po,.'tio::s of the 
microfilm masters or the softcopy would be provided in 
microfilm form upon request. 
A catalog will be one of the elements in the co2.1ection. It will 
list all material in the collection, whether it exists as softcopy, 
.hardcopy, or ny co:bination.

------------------------------<page break>-----------------------------
(3) A ]1ocumentatio:'~.Aid ' .- ' 
The system , oriented to typewriters , ' will inco.r'ooratc text 
editing and  " 
e restructu'ins facilities similar to those .now available 
in t){e I3[!RC On Line Systen (i[LS). -- 
The hierarchical structure, basic to the concept of thc NLS: will 
be available for use in all documents held by the NIC. (It may, of 
.course,be used simply as a list of !m. ragraphs headings, etc.) The 
d0c%a-..etation-aid system will a'ssist the user in 6ener{.ting and using 
doc.ents that exploit the possibilities of this structure. 
-A transcription service will be avai!ab],e at the NIC to trenscribe 
ha/'dc'opy documents into a softcopy vetsign to be held in the NIC. This 
service will permit the inititc! entry into the NiC held corpus of large 
.numbers of existig doc..:ents and newly ge:e-aed doumcn",;s (at least 
d%n'ing[the initial phase of the network) without unduly burdening the 
user. It will provide a transition intePva]. while users become 
acquainted with the NLS dock, lent structuro formt. Uitimzteiy it is 
 assumed that docunents will be originally written with the lse of 
computer aids -- either on the user's computer or with NIC's 
docmment-ai d system. 
(4) A Query and Search System 
This system will be applicable to softcop,'; nd hardcopy versions of 
the collection. By means of the "content analyzer" (a feat'c of the 
present NLS) the user will able to construct content specifications for 
searchin the NIC collection. 
By ..ns of links between doctu:ents and within any one docm*,ent 
(anot. her fatue of the present i{LS) the user will be able to follow 
l:r. edetermined "trails" through the i;IC collection. 
Plans are being made to develop a NIC catalog, encompassing the 
softcooy and hardc0)y (microfilm) versions of the collection. 
.... ' (5) A Retrieval and Outw. ut System 
This  system will have online, offline, softcopy, and hardcopy 
(microfilm) applications. 
The user will be able to request a "copy" of the docu,,ent for his 
use. "This may be a softcopy for use through NIC amds, or for use at 
o'^n. computer, ".

------------------------------<page break>-----------------------------
The user .may also make special requests for hardcopy versions 
either on microfilm or on paper, both produced at %he LIC. If he 
obtains a copy of the file at his machine he can, of course: produce his 
own ha'dcopy version, 
It is expected that the user will typically desire selected "views" 
 of the document rather than the entire doc:e:':t itself. A vie;.: can be 
1oecified as to depth in t}e hierrc}tiel file tructure, trunctrton 
(number of lines of ech sttenont), mud section or sectiotas of the file 
or files. 
The view i13. be chosen by the user ,d will depend upon the depth 
with which he wishes to e:.:onine the docur.',ent and. the type of terminal at 
his disposal. A typewriter user will desire smaller vo],umos of material 
them will the CRT user, because of the s].o.; speed of the terminal; the 
range of oossible views will reflect this, 
IV INITIAL PJ...i[$ 
Users to be Served 
The initial plan covers the period from the present to December 
1969. During this interval the network will be in its deve].ol?,.ental 
stage and will be unavailable for general use. The parties concerned 
with this dev'elop.-..ent will be ARPA, BBU (the net.*ork contractor), and 
the fu/' initial sites (b11AH, UCSB UCLA SRI), These parties are the 
prima users to be served ding this time with the emerging 
services. .IC's specific service feats'es are being oriented toward the 
needs of these users. Users at the other 15 sites are expected to use 
the NIC to a lesser degree during this period, but will become 
increasingly active ding the latter part of 1969 and throuEh 1970. 
Initial Services 
The focus of the NiC will be upon the development of its basic 
collection of doeunents, a Typewriter-Orie.nted DocLmentation-,Aid System 
(TODAS), end a early version of the on-line. search arid retrieval 
process, 
Information in the initial collection is being oriented to 
docuuents pertaining to the network develop.-..ent, and to descri!,t.io:s of 
systems and subystems to bc avail. able at the initial site;. This 
information consists of procra:?, docur.ent,.tio:'., system detcriptio:m, u:;cr 
manuals, protocols md proeedurcr,, and ?,tat'.:s reports. 
A /,iC transcription service is already 
transcribing these doct'.ents into the

NIC EWSLE?TER 
January 1969 
A preliminary version of the Typewriter Oriented Document Aid 
System (TODAS), is now in use by the transcription service, operating in 
the off-line mode only. 
Quite early, about the 2nd quarter of 1969, the collection will be 
made available to the users in microfilm form. At that time a NIC 
system, called Graphics-Or.iented Document Output System (GODOS) will 
enable computer-held information at the NIC to be recorded onto 
mi6roftlm via a .CRT. 
During the third quarter of 1969 an on-line version of TODAS should 
be implemented to permit users with Teletype machines on the dialup 
telephone network to call into the NIC and execute a limited search 
During the last quarter of 1969 the on-line version of TODAS with 
text-manipulation capabilities should be available. 
Present Collection 
The present NIC collection contains (in softcopy form) all or 
portions of the following documents:
